Anopfuura makore gumi apfuura, vanhu vazhinji vangadai vasina kufunga kuti chiedza uye hutano zvingave zvine hukama. Mushure meanopfuura makore gumi ebudiriro, iyoMwenje we LEDindasitiri yakawedzera kubva mukutsvaga kushanda kwechiedza, kuchengetedza simba uye mutengo kusvika pakuda kwemhando yechiedza, hutano hwakareruka, mwenje biosafety uye mwenje nharaunda. Kunyanya mumakore achangopfuura, matambudziko ekukuvadza kwechiedza chebhuruu, rhythm disorder uye kukuvara kweretinal yevanhu kunokonzerwa ne LED zviri kuramba zvichinyatsojeka, izvo zvinoita kuti indasitiri ione kuti kufarirwa kwechiedza chine utano kunokurumidza.

Biological hwaro hwemwenje wehutano

Kazhinji, chiedza chehutano ndechekuvandudza nekuvandudza kushanda kwevanhu, kudzidza uye mararamiro uye hutano kuburikidza nemwenje we LED, kuitira kusimudzira hutano hwepfungwa uye hwepanyama.

The biological mhedzisiro yechiedza pavanhu inogona kupatsanurwa kuita zvinoonekwa uye zvisiri zvekuona maitiro.

(1) Kuonekwa kwechiedza:

Chiedza chinooneka chinopfuura nepacornea yeziso uye chinofananidzirwa pane retina kuburikidza nelens. Inoshandurwa kuita zviratidzo zvemuviri nemasero ephotoreceptor. Mushure mekuigamuchira, tsinga yemaziso inogadzira kuona, kuitira kutonga ruvara, chimiro uye chinhambwe chezvinhu zviri muchadenga. Vision inogonawo kukonzera vanhu psychological mechanism reaction, inova mhedzisiro yepfungwa yekuona.

Kune marudzi maviri emasero anoona: rimwe masero ekoni, anonzwa chiedza uye ruvara; Rudzi rwechipiri masero akaita setsvimbo, anogona kungonzwa kupenya, asi kunzwisiswa kwakapetwa ka10000 kune kwekutanga.

Zvizhinji zvinoitika muhupenyu hwezuva nezuva ndezvekuona kwechiedza:

Imba yekurara, imba yekudyira, chitoro chekofi, chiedza cheruvara chinodziya (sepingi uye chepepuru chakareruka) chinoita kuti nzvimbo yese ive nemhepo inodziya uye yakasununguka, uye inoita kuti ganda nechiso chevanhu zvitaridzike zvine hutano panguva imwe chete.

Muzhizha, chiedza chebhuruu uye chegirini chichaita kuti vanhu vanzwe kutonhorera; Munguva yechando, tsvuku inoita kuti vanhu vanzwe vachidziya.

Kuvhenekera kwakasimba kwemavara kunogona kuita kuti mhepo ishande uye kujeka, uye kuwedzera bishi remafaro.

Makamuri emhuri emazuva ano anowanzo shandisa mamwe magetsi ekushongedza matsvuku uye egirinhi kushongedza imba yekutandarira neresitorendi kuti awedzere mhepo inofadza.

Mamwe maresitorendi haana chiedza chese kana chandelier patafura. Vanongoshandisa mwenje wekenduru isina kusimba kuti vabvise mhepo.

(2) Zvisiri zvinoonekwa zvechiedza, kuwanikwa kweprgc:

Kune rudzi rwechitatu rwemafotoreceptor masero muretina yemunhu - mukati mafotosensitive retinal ganglion masero, ayo ane basa rekudzora zvisizvo zvisingaonekwe kunze kwekuona kwemuviri, senge basa rekutonga nguva, kuronga nekudzora rhythm yezviitiko uye amplitude mune dzakasiyana. nguva dzenguva.

Iyi isiri yekuona maitiro inonziwo sichen visual effect, iyo yakawanikwa naBerson, Dunn naTakao vekuBrown University mumhuka dzinoyamwisa muna 2002. Ndiyo imwe yepamusoro gumi yakawanikwa pasi rose muna 2002.

Zvidzidzo zvakaratidza kuti kusaonekwa kwemakonzo emumba ndeye 465nm, asi kuvanhu, zvidzidzo zvemajini zvinoratidza kuti inofanirwa kunge iri 480 ~ 485nm (nhongonya dzemaseru ekoni uye masero etsvimbo i555nm uye 507nm, zvichiteerana).

(3) Nheyo ye iprgc inodzora biological wachi:

Iprgc ine yayo neural transmission network muuropi hwemunhu, iyo yakasiyana zvakanyanya nekuona neural transmission network. Mushure mekugamuchira chiedza, iprgc inogadzira zviratidzo zvebioelectric, izvo zvinotumirwa kune hypothalamus (RHT), uye zvino pinda musuprachiasmatic nucleus (SCN) uye extracerebral nerve nucleus (PVN) kuti isvike pineal gland.

Iyo pineal gland ndiyo pakati pehuropi hwebhayoloji wachi. Inoburitsa melatonin. Melatonin inogadzirwa uye inochengetwa mupineal gland. Kufarira kunzwira tsitsi kunokanganisa masero epineal kuti abudise melatonin muropa rinoyerera uye kukonzeresa kurara chaiko. Naizvozvo, ihomoni yakakosha kugadzirisa physiological rhythm.

Iyo secretion ye melatonin ine iri pachena circadian rhythm, iyo inorambidzwa masikati uye inoshanda usiku. Nekudaro, iyo excitability yekunzwira tsitsi tsinga inowirirana zvakanyanya nesimba uye ruvara rwechiedza chinosvika papineal gland. Rudzi rwakareruka uye kusimba kwechiedza kuchakanganisa kuvanzika uye kuburitswa kwe melatonin.

Pamusoro pekugadzirisa wachi yebhayoloji, iprgc ine chekuita nekurova kwemoyo wemunhu, BP, kusvinura uye simba, zvese zviri zvekusaona maitiro echiedza. Pamusoro pezvo, kukuvadzwa kwemuviri kunokonzerwa nechiedza kunofanirwawo kuverengerwa nekusaonekwa kwechiedza.
